...hmm...are not Facebook and Twitter owned by private entities, therefore, they can censor whomever they want???
It would become a state law perhaps, but they would be able to ban his posts in all the other states?
No. They are public utilities and need to be treated as such.
The power company cannot turn off someone's power just because they're an American.
The gas company cannot turn off someone's gas just because they're an American.
And the public square cannot be closed to the people who are pro-Americans just because the fascists controlling the roads to the square are racist Democrats. The First Amendment guarantees the right of the people to peaceably assembly and petition their government to redress grievances.
The fascists at Fakebook, Twattor, YouTube, Google and the rest cannot both claim to be the communications nexi of the world and then claim to be independent businesses who are free to engage in whatever racism they feel best promotes their self-interested causes.
So, screw'em. They want to be shills for fascists? Then they can get treated like the fascists they are. Remember what happened to Mussolini? If we can't get them to do the Hitler Exit, then we have to consider practical alternatives to their tyranny.
